The electrostatic potential is determined for a test electron with {upsilon}{sub {parallel}} {much_gt} {upsilon}{sub Te}, in a uniform magnetized plasma ({omega}{sub ce} {much_gt} {omega}{sub pe}). In the frame of the test electron, part of the spatially oscillatory potential has spherical symmetry over the hemisphere to the rear of the electron and is zero ahead of the electron. A second part of different character, which makes the potential continuous at the plane containing the electron, is oscillatory in the radial direction but decreases almost monotonically in the axial direction.
